Our light rail fish plates are a better and cheaper option than welding. They are designed to be easy to install with matching fish bolts, which cuts down on labor costs and the time it takes to get the track. The arched bridge design is a key feature that was created to absorb shock and lessen the effect of wheels going over the joint. This makes the rail more continuous along its length, which means less wear on track parts and a smoother, safer ride. Our fish plates guarantee better performance and longer life for modern light rail systems by making train passage more stable and extending the life of your track.
